The FBI was interviewing a Milwaukee resident Thursday believed to be responsible for posting what officials think are phony threats on a Web site about radiological dirty bomb attacks on NFL football stadiums this weekend.

The person, described only as a young adult, did not appear to have any ties to terrorist groups, according to a law enforcement official who spoke on condition of anonymity because the investigation was ongoing.

The threats, which were posted on the Internet site a week ago, were not seen as credible and were not backed up by intelligence indicating such an attack might be imminent, according to the FBI and the Homeland Security Department.

Authorities traced the site’s Internet provider to Voxel Dot Net Inc., which has support and engineering staff based in Troy, N.Y. A man who answered the phone at Voxel Wednesday declined to give his name, said he was unaware of the posted threat and refused further comment.

The author of the threats, posted at 9:31 p.m. EDT on Oct. 12, identified himself online as “javness.”

Let this be a lesson to the Green Bay Packers and the great American Devil Brett Favre : there are grave repercussions for your mistreatment of Javon Walker (above).

Or, perhaps some kid was bored. Either way, I admire the courage shown by the league in confirming the threat and assuring the public these (mostly sold-out) games are perfectly safe.
